SQL: получить результаты временных рядов дней назад

0 голосов
/ 16 октября 2019

Приведена таблица значений запасов для сущностей, сохраняемых каждый день. Я хотел бы получить:

Дайте всем организациям, которых нет в наличии (Кол-во = 0) сегодня и не было в наличии накануне.

И это по сравнению со вчерашним днемнакануне вчерашнего дня. И так далее.

Мой подход работает, но мне нужно вручную создать деталь в условии WHERE.

Как насчет запроса на весь 2019 год?
